Application filed October 2, 1913. Serial No. 793,002.

To all whom 'it may concern Be it known that I, AMEEN Aron, a citizen ofthe United States, residing at Spokane, in the county of Spokane, Stateof Washington, have invented certain new and useful Improvements inAttachments for ciewing-lelachines, of which the following is aspeciiication.

My invention relates to attachments for sewing machines and it providesa fan device which is simple in construction, cheap to manufacture, andeasily attached `and detached to or from any sewing machine. It providesa means of circulating the air in the room, in which the sewing machineto which the device is attached stands, and it eliminates the expense ofproviding an electric fan or other means of circulating the air.Furthermore it only requires an inappreciable amount of power tooperate. It is particularly advantageous in tailor shops anddressinakers establishments where one or more sewing machines areoperating in a room where a number of people are working, for it servesto keep the atmosphere in motion, and the machines may be distributedthat the fan on one machine will cool the operator of another machine.

Referringto the drawings attached hereto and forming a part of thisspeciiication: Figure 1 shows a fan constructed according to myinvention and applied to a sewing machine. Fig. 2 is a front elevationof a fan constructed according to my invention. Fig. 3 is a sideelevation view of the fan shown in Fig.y 2. Fig. 1 is a rear elevationview of the fan. Fig. 5 is a view similar to that shown in Fig. 2 butshowing the fan in a position to show the lugs of the clamping member.Fig. 6 is a section on line X-X pf Fig. 2. Fig. 7 is a modified form ofmy an.

An embodiment of my invention shown in the drawings consists of a fanhaving a number of blades l, 2, 3 and i disposed radially from a centralportion 5. To the central portion 5 of a fan l attach a clamp member 6.This clamp member 6 consists of a circular sleeve portion formed inthree parts. r1`he part 7 carries integral therewith the bent arms 8 and9 connected by the member 11 integral therewith. The fan is carried bythe connecting portion l1 and is secured thereto by any suitable meanssuch as the stud 10 extending through the fan and secured by the nut.rThis stud 10 is integral with the portion 11 connecting the arms 8 and9, and it also carries the projecting pins 12 and 13 thereon which eX-tend through holes drilled in the central portion of the fan. These pinsserve to keep the fan from turning on the stud 10 and with respect tothe clamp member. The member 7 of the clamp carries the two parts 14 and15 hinged thereto at 16 and 17, respectively. These hinged parts serveto complete the sleeve portion of the clamping member and also carry theupstanding lugs 18 and 19 through which the bolt 20 passes. Thisclamping member is adapted to go onto the drive shaft 21 of the sewingmachine 22, and when the clamp is tightened up by means of the nut 23yon the bolt 20 the fan will revolve when the sewing machine isoperated.

It will be seen different sizes of fans may be substituted on the clampby simply removing the nut from the stud 10 and putting on another fanadapted to fit on the pins and stud.

I may find it preferable in adapting my invention to light householdsewing machines to construct the fan as shown in Fig. 7, of a metalframe work 24 and cover the blades with fabric 25, instead of using ametal fan.

It is understood that l do not limit myself to any particular type ofsewing machine or shape of fan, but may make such modiiications as fallwithin the scope Vof my claims.

What I claim is:

1. An attachment for sewing machines comprising in combination, aclamping member consisting of a split sleeve portion, abow integraltherewith and extending outwardly therefrom, lugs integral with saidbow, hinge members mounted on the edges of the split in said splitsleeve and adapted to be clamped together, a fan having aperturestherein adapted to receive said lugs, said fan being adapted to bemounted on said bow, and means for securing said fan in place.

2. An attachment for sewing machines comprising in combination, aclamping member consisting ,of a split sleeve portion, a bow integraltherewith and extending outwardly therefrom, lugs integral with said bowand adjacent the central portion thereof, a stud mounted on said bow andconcentric with the axis of said split sleeve, In testimony whereof I aXmy signaolamping means for said split sleeve, and ture in presence oftwo Witnesses, a fan having therein apertures adapted to AMEEN AYOB. titover said lugs, said fan being adapted Witnesses:

5 to be retained on said bow portion by means WM. E. LEE,

of said stud. A. J. SIMONSON.
